Potencial enológico de seis castas brancas regionais de Trás-os Montes cultivadas na sub-região de Valpaços
| Resumo: | In order to contribute to the revitalization of the white varieties existing in the wine region of Trás-os-Montes and consequently produce wines with different characteristics in this region, the oenological potential of Bical, Códega do Larinho, Donzelinho Branco, Vital, Rabigato and Viosinho, planted in Valpaços sub-region from Trás-os-Montes, was evaluated and compared . Through a microvinification, monovarietal wines were produced with the varieties listed thereafter. During the production, half of the must that was obtained by each variety, was inoculated with commercial yeast and the other half fermented spontaneously. Later on, analytical determinations were completed and a sensory analysis panel was gathered in order to assess the organoleptic characteristics of the wines, through a blind tasting, according to the tasting notes prepared beforehand. The physicochemical and sensory results were statistically analyzed. The results enable us to find other oenological differences between the different wines, but, despite these differences, we can conclude that all the varieties have a good oenological potential, which indicates that they have intrinsic qualities that should be enhanced. |
